Question

Which of the following has the largest number of atoms?
a. 1g Au (g) b.1g Na (g) c. 1g Li(g) d. 1g of Cl2 (g)

Answer 1

Answer:

1g of cl2 has large no. of atoms

Answer 2

Explanation:

Answer:-

(i) 1 g Au = 1/197 mol = 1/197×6.022×1023 atoms

(ii) 1 g Na = 1/23 mol = 1/23×6.022×1023 atoms

(iii) 1 g Li = 1/7 mol = 1/7×6.022×1023 atoms

(iv) 1 g Cl2 = 1/71 mol = 1/71×6.022×1023 atoms

Thus, 1 g of Li has the largest number of atoms.
